The blackening of the gold plating layer on the PCB board commonly occurs during the copying process, and the problem can be analyzed and addressed through controlling nickel coating thickness, solution for nickel plating cylinder, and gold plating bottle control, as well as considering the PCB board layer types, design requirements, and optimizing the PCB board layer.
Rigid-flex PCB combines the characteristics of both flexible circuit boards and rigid circuit boards, providing small size, flexible design, better mechanical stability, performance in harsh environments, ease of manufacture and testing, and customization for different applications, making it widely utilized in high-end smartphones, intelligent wearable devices, aerospace, and other fields.
